SPECIFICATION forming part of Letters Patent No. 715,709, dated December 9, 1902,

Application filed May 29| 1'902. Serial No. 109,563. (No model.) 4

o all) whom t may concern:

Bo it known that LWILLIAM F. Tosca, a citizen of the United States, residing at Cobden, in the county of Brown and State of Minnesota, have invented a new and useful Engine, of which the following is a specification.

This invention relates generally to engines,

Aand more particularly to that class known .as

rotary engines; and the object of the invention is to provide a cheap and simple construction of engine having a governor' attachment in connection therewith, whereby speed can `be maintained at a uniform degree; and another object of the invention is to provide for the reversal of the said engine.

With these objects in view the invention consists in the novel features of construction, combination, and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this speciication, Figure l is a perspective View of an engine constructed in accordance with my invention. Fig. 2 is a vertical sectional View. Fig. 3 is a detail sectional view, partly in ele- Vation. ing the manner of operating steam -inlet valves.

In constructing an engine in accordance with my invention I employ a cylinder A, to which is securely bolted the heads B, and mounted in the said heads is a shaft C, having a hub I) arranged thereon and from which radiate the V-shaped piston blades or wings E, said blades or wings having their concaved faces arranged alternately in opposite directions, so that the piston can be rotated in either direction, as more fully explained hereinafter. The V-shaped blades or Wings E are arranged between the pair of circular plates of disks F, which fit closely against the heads of the cylinder and are of such size as to iit snugly within the body of the cylinder, thereby providing a series of pockets into which the steam is projected for the purpose of rotating the piston.

The main steam-pipe G has a T-coupling G', from which extend the branch steam-pi pes G2 and G3, the pipe G2 entering the cylinder adjacent to the upper end, while the pipe G3 enters the cylinder adjacent to the lower end.

Fig. 4 is a sectional view illustrat- G4 and G5 indicate exhaust-pipes correspending with the inlet-pipes G2 and G3, respectively, said pipes G4 and G3 being connected to a common exhaust-pipe G6.V

Ordinary globe-valves H are arranged in the pipes G2 and G3, and by means of which the supply of steam can be completelycut off from the said pipes. Regulator-valves I and I are arranged, respectively, in the pipes G2 and G3, the stems I2 and I3 of said valves being connected to each other at I4, and these stems are also connected to the adjustable rod K of the governor L, arranged upon the pipe G2, said governor being supported upon a suitable bracket L and operated through the medium of a shaft K', carrying a pulley K2, over which travels a belt K3, receiving its motion from the pulley K4, mounted upon the shaft C, said shaft being journaled in suitable bearings C', arranged upon opposite sides of the engine-cylinder. By having the valve-stems of the regulating-valves connected to each other and also to the governorrod it is obvious that only the governor is needed for Athe regulation of my improved construction of engine.

TheV branch pipes G2 and G3 are employed in order to permit the engine to be run in either direction, it being understood that the steam entering from the pipe G2 will drive the piston in one direction, while the steam entering through the pipe G3 will drive the pis- 'ton in the opposite direction, and by having the piston-blades arranged alternately With reference to their concaved faces it is obvious that every other piston-blade or wing will be operated upon by the jet of steam. When steam is passing to the engine through one pipe, the other pipe is of course kept closed.

The governor only operates upon one pipe at a time, inasmuch as steam is only passing through one pipe at a time.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a rotary engine, the combination/With I the branch steam-pipes entering the enginecylinder at different points, of the regulating- `valves in said steam pipes, the governor mounted upon one of the said pipes, the stems of the regulating-valves being connected with IOO alternately in opposite directions, the stealn- 1o inlet; pipes and exhaust-pipes connected to the cylinder, substantially as and for Iche purpose described.
